Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Physics Questions
Read full descriptionHide full description
Best tool for school or college for practising all those physics questions! This app will help you to learn about the different concepts in physics. With separate modules for each subject area, you can practice: ---> Electricity ---> Electronics ---> Electromagnetism ---> Force & Energy ---> Motion ---> Optics ---> Radioactivity & Thermodynamics ---> Special Relativity ---> Waves & Particles At the press of a button, you can be prompted with the correct formula as well as being shown the worked solution.

Experience the hidden world of particles Quantum is a real-time particle life sandbox for exploring emergent motion, artificial physics, and complex systems. Build fields with up to 10,000 particles, tune how classes attract or repel each other, and watch simple rules turn into flowing structures, swarms, or chaotic patterns. Why Quantum stands out: - Real-time particle simulation with four interacting particle classes. - Seamless 2D fields and perspective 3D volumes with touch rotation. - Rule editor for custom attraction and repulsion matrices. - Temperature, viscosity, solid/fluid edge behavior, and force tools. - Black hole and white hole tools for live interaction. - Save and load fields, rule sets, and color schemes. - P3 color support and vivid visual presets for generative art. Use Quantum as a physics toy, creative sandbox, teaching aid, or generative art lab. It is built for people who enjoy science, cellular automata, n-body systems, chaos, and beautiful simulations.

Verdict
The clearest difference is ads: Quantum at none against Physics Questions's shown. Physics Questions's advantage is update cadence (every 4 days vs every 5 weeks) and iOS requirement (12.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Physics Questions sells 9 one-off in-app purchases and Quantum sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
Physics Questions ships an update every 4 days, Quantum every 5 weeks. The most recent releases landed on September 19, 2026 and September 23, 2026 respectively.
